is the equation in the question written like the one in the bottom? Because for me to help you I must confirm what the equation looks like.

$\frac{a-3}{2a^{2} -7a}$ × $\frac{4a-14}{a+3}$

Answer:

The term (2a-7) can be cancelled.

Step-by-step explanation:

We are given the following expression and we are to simplify it and see which terms get cancelled out:

$\frac {a-3} {2a^2 - 7a }$ × $\frac { 4a - 14} {a + 3}$

Taking the common terms out to simplify it:

$\frac{a-3}{a(2a-7)}$ × $\frac{2(2a-7)}{a+3}$

Here, the term $(2a-7)$ get cancelled so we are left with:

$\frac{2(a-3)}{a(a+3)}$

pav-90 [236]

Answer:

See below ~

Step-by-step explanation:

Question 1

-7x - y = -1
y = 8x + 16

⇒ -7x - (8x + 16) = -1

⇒ -7x - 8x - 16 = -1

⇒ -15x = 15

⇒ x = -1

⇒ y = 8(-1) + 16 = 8

⇒ Solution = (-1, 8)

Question 2

3x + 4y = 0
y = -3x - 18

⇒ 3x + 4(-3x - 18) = 0

⇒ 3x - 12x - 72 = 0

⇒ -9x = 72

⇒ x = -8

⇒ y = -3(-8) - 18 = 6

⇒ Solution = (-8, 6)

Question 3 (not clear)

Question 4

-8x - 7y = 0
y = 6x

⇒ -8x - 7(6x) = 0

⇒ -8x - 42x = 0

⇒ -50x = 0

⇒ x = 0

⇒ y = 6(0) = 0

⇒ Solution = (0, 0)

Question 8

2x - 6y = -14
y = -5x - 19

⇒ 2x - 6(-5x - 19) = -14

⇒ 2x + 30x + 114 = -14

⇒ 32x = -128

⇒ x = -4

⇒ y = -5(-4) - 19 = 1

⇒ Solution = (-4, 1)

5 out of 20 students said ice cream was their favorite snack if they were a hundred six graders how many would chose ice cream P

Rufina [12.5K]

Answer:

25 students

Step-by-step explanation:

20 times 5 equals 100

5 times 5 equals 25

To get to 100 students you would times it by 5 and because we times'd the 20 times 5 we need to do the same to the 5 which would result in 25 students. Hope this helped! xx
